HORSE-POWER FOR GINS, 80b.

SPECIFICATION forming part of Letters Patent No. 233,244, dated October 12, 1880.

Application filed July 222, 1880.

To all whom it may concern Be it known that I, WILLIS H. HARVEY, a citizen of the United States, residing at Somerville, in the county of Fayette and State of Tennessee, have invented certain new and useful Improvements in Horse-Powers for Gins, &c.; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanyin g drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to an apparatus for transmitting motion from a prime motive power to the machinery intended to be driven thereby; and it has for its object to simplify the construction of such mechanism and reduce theexpense of the same. 7

The invention is designed as an improvement upon the device set forth in the Patent No. 229,407, granted to me J nne 29, 1880.

The object of this invention is to provide such an adjustability upon one or more of the pulleys as will not only take up the slack of the belt, rope, or cord, but will exert, by means of a weight or a spring, a constant force upon the pulley-friction.

ln the accompanying drawings, which form a part of this specification, Figure l is a front elevation of my improved apparatus. Fig. 2 is a top or plan view; and Fig.3, aperspective detail view of my adjustable pulley, the weight, and its attachments.

Referring to the drawings, A represents the base, B the vertical standards, and E the horizontal top bar, which form a supportingframe. These parts may be of any proper number, and arranged in relation to each other as may be preferred.

J ournaled above and below in the frame is a revolving shaft, 0, carrying a sweep, G, to which the draft animal or animals are attached for operating the machine.

Secured upon and rigid with the shaft 0 is a horizontal pulley, F, braced at said pul- ,ley being grooved at its periphery to receive the operating-rope. Adjacent to this pulley F is a vertical pulley, H, rigid upon a horizontal shaft, I, journaled in the frame. These parts are preferably arranged at or near the (No model.)

center of the frame; but such arrangement may be modified to locate the pulley H upon one end of the machine, and secure advantageous results, if desired, as seen in dotted lines, Fig. 1.

L represents a horizontal pulley upon a shaft, L, journaled in. brackets L which form part of the frame. The upper bracket, L forms a frame having guides, in which slides a movable frame carrying a pulley, P, arranged vertically and hung upon a shaft, R.

Arranged in the stationary frame L is a shaft, 00, carrying a pulley, ac, over which 0perates a rope, 11 having upon its free end a weight, .10 as shown.

V represents an endless band, cord, or chain. which passes around the horizontal drivingpulley F, then around the pulley L, and finally around the vertical pulleys, and by means of this construction and arrangement a horizontal rotary motion may be converted into a vertical rotary motion for any desired purpose.

It will be observed that the weight .90 exerts a constant force to take up the slack in the rope and tends to compensate for Wear and stretching, and in this feature and its relation to the complete apparatus lies the gist of the invention.

Upon the shaft I, adjacent to the pulley H, is a band-wheel, U, by means of which motion and power may be conveyed to cotton-gins and similar machinery.

What I claim as new is 1. In an apparatus for transmitting motion from a prime motor to machinery, the horizontal pulley F, rigid upon the shaft 0, the horizontal pulley L, the two pulleys P H, and endless band V, combined with means for taking up slack in the band and adjusting pulley-friction by a constant force. as specified.

2. The combination of the shaft 0, the pulleys F L P H, as shown, the frame L the sliding frame and pulley P, pulley w x, rope x and weight 92 all operating as and for the purposes specified.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIS H. HARVEY.
